Couple of questions:
What thickness torsion bars did you have on it prior to going with coil-overs?
*Have you calculated the c/o spring pressures to match the prior torsion bars? There is a formula floating around with how to do this, but I cannot find the dang article.
Do you have access to a set of corner scales?
As RRR mentioned, full weight on final tightening will make a huge difference. I use the 14" Race Ramps so I can squeeze my fat *** underneath the car to make adjustments.
